This is the simple spring boot maven hello project that contains a REST API to test the project is running successfully. It contains the concourse_ci directory that contains all about the concourse CI/CD pipeline.

prerequisite

• Docker
• Docker Compose
• Maven
• Kubernetes Cluster
• Docker Hub Account

local testing

Run mvn clean package Then run java -jar target/hello-springboot-0.0.1-SNAPSHOT.jar

Now Spring boot application is running locally, Verify it by hitting the below URL

http://localhost:8080/api/hello

First, you need to give the following variable value in the config.yml file

Docker

docker-hub-email: <>

docker-hub-username: <>

docker-hub-password: <>

docker-hub-repo-name: <>

Kubernetes

server: <>

namespace: <>

cad: <>

token: <>

then save the file on local, Don't push it to the repository and you can also use vault as a secret manager.

• Download the Docker compose file

    `wget https://concourse-ci.org/docker-compose.yml`
  

• Run the Docker Compose File

    `docker-compose up -d`
  

• Download the fly CLI tool from the localhost:8080

• Give execute permission to the fly CLI

    `chmod +x fly`
  

• Copy the fly CLI to the /usr/bin

    `sudo cp fly /usr/bin/`
  

• Login to the concourse

    `fly -t ci login -c http://localhost:8080 -u test -p test`
  

• Clone the following spring boot project

    `git clone https://github.com/prasad459/concourse-ci-cd.git`
  

• Change to the root dir of the project

    `cd concourse-ci-cd`
  

• Create Concourse Pipeline

    `fly -t tutorial set-pipeline -p spring-boot-service -c concourse_ci/pipeline.yml -l concourse_ci/config.yml`
  

• Unpause Concourse Pipeline

    `fly -t tutorial unpause-pipeline -p spring-boot-service`
  

Now you have successfully setup the CI/CD pipeline that test, package and deploy your project to the Kubernetes.
